Abstract
The aim of the research was to analyze the dynamics of morphometric parameters of the epithelial component (parenchyma) of the mammary gland of sheep and pigs in postnatal ontogenesis. The object of the study was the mammary gland of sheep of the Stavropol breed and pigs of a Large White breed at the age of 1 day (newborns), 3, 6, 9 and 12 months. As a result of the studies, it was found that the area of ducts in the mammary gland in sheep of the Stavropol breed in postnatal ontogenesis varies from 250.80 ± 45.48 µm 2 to 2503.00 ± 533.70 µm 2 , and in the mammary gland in pigs of Large White breed-from 602.10 ± 106.00 µm 2 to 9134.00 ± 1099.00 µm 2 . Identical dynamics of changes in the area of epithelial cells and their nuclei in postnatal ontogenesis were revealed in sheep and pigs. The minimum average values of the epithelial cell area in sheep were detected at twelve months (26.45 ± 1.14 µm 2 ), and the maximum values at nine months (39.28 ± 1.48 µm 2 ). In pigs, this parameter was the lowest at six months (30.69 ± 0.39 µm 2 ), and the highest in diurnal and nine-month-old individuals (42.39 ± 2.51 µm 2 and 42.07 ± 0.97 µm 2, respectively). The average values of the core area of mammary epithelial cells in sheep were minimal at twelve months (11.51 ± 0.55 µm 2 ), and maximum at nine months (18.41 ± 0.82 µm 2 ). In pigs, this parameter was the lowest at twelve months (13.30 ± 0.64 µm 2 ), and the highest in nine-month-old individuals (18.42 ± 0.46 µm 2 ). The nuclear-cytoplasmic ratio of sheep mammary glad epithelial cells was maximal in three months of life, and minimal in diurnal and six-month-old animals. In pigs, this indicator was the maximum in nine months of life, and the minimum in twelve months. This information can be used as a constant data for specialists of sheep and pig farms in the North Caucasus when raising sheep of the Stavropol breed and pigs of a Large White breed.
